A series of novel 2-imino-4-thiazolidinone derivatives 4a,b was synthesized through reaction of unsymmetrical thioureas 3a,b with chloroacetic acid. Condensation of 4a,b with aromatic aldehydes 5a-eyielded the corresponding 5-arylidene derivatives 6a-j. In addition, the reaction of 4a,b with 4-arylazo-3-hydroxybenzaldehydes 8a-c furnished the respective mono-arylazo-4-thiazolidinones10a-f. All the
通过不对称硫脲3a,b与氯乙酸反应,合成了一系列新型的2-亚氨基-4-噻唑烷酮衍生物4a,b。4a,b与芳族醛5a缩合,生成相应的5-亚芳基衍生物6a-j。另外,4a,b与4-芳基偶氮-3-羟基苯甲醛8a-c的反应提供了相应的单芳基偶氮-4-噻唑烷酮10a-f。所有新合成的化合物均通过其元素分析和光谱数据证实。评估了新合成的化合物的抗真菌活性,并且化合物6d,6e,6i,6j,9a,b和10a的抗真菌活性比标准Ridomil gold plus高。此外,4-噻唑烷酮衍生物6d,9a,10b,在Solanternate solani(KT354939)的核酸上进行了10c和10f的鉴定,结果定性地显示了超过70%的裂解。同样,化合物6i,6j,9b,10c和10f停靠在1ZOY酶的活性位点内,并根据其键长,角度和构象能显示出与氨基酸活性位点的适当结合。
